why study Human–Computer Interaction

This video looks at a variety of examples to explore the different reasons why human-computer interaction is an important and exciting area to study.

Activity: who is to blame

When I messed up drawing the line in the video, whose fault is it? Is it the Google designers' fault, for making a poor design, or my fault for not being careful enough?

Imagine that instead of simply meaning I drew a line in the wrong place it had been far more serious,perhaps someone got killed because of the mistake. There is a court case and imagine you are being the lawyers.

First think of the arguments my lawyter might make for why it is the web site's fault.

Then take Google's part and think of all the arguments they might bring for the web site being well deisgned and it being 'human error' on my part.

Finally, taking into account (1) and (2) suggest any ways you think the page could have been designed better, or maybe I could use it better, so that mistakes like this do not happen again.

Trust is a fickle thing, hard to build up, but so easy to lose. It is crucial for all websites, but particularly those that involve money or personal data and reputation including social networks. This case study concerns the first stages of use of an academic social network site. We look through the factors that build and lose trust. Social networking web sites depend on viral growth, if potential users are lost in the early stages, then the growth of the community is threatened.

bad usability can kill

Here are some links connected with medical instruments and infusion pumps in particular. However, this is an issue whenever people have to use technology in safety critical situations.

CHI+MED (Computer-Human Interaction for Medical Devices) is multi-University project to improve the safety of interactive (programmable) medical devices, such as infusion pumps. By understanding more about device design and human factors, medical errors can be reduced thus saving lives.
